This invention' mlm@ to eheh regime, v and more particularly to the totalizer mech- -anismthereoi One object of this invention istoprovide 5 adding and subtracting totalizer for use with cash registers, whchtotalizer is more compact and practical than those now in use. f Another 'ob'ect is the construction of an adding and su tracting totalizer whose units ed' and placed in the e, or assembled in position in the machine. Another ob'ect is the construction of anadding and su tracting totalizer requiring a i5 small amount of movement between adding and subtracting positions.

With these and incidental objectsin vlew" and therefore only such ofthe mechanism as is considered necessary vproperly to show the operation of the invention' is included 'in this application. V .A

In the Fuller patent above mentioned there is shown, anadding and subtracting the invention consists of certain novel 'fea-- ,tures of construction ,and -combinations of f so parte, the essential elements of which. are set orth in appended'claims anda preferred form or embodiment of which hereinafter describedV with reference lto e drawing meuh adding an unie wich `pai-tof thelnechanismthereofbro naway..

totalizer including ltwo Jordinary 4totalizer lse wheels, such as is usual in these machines,

having bevel ears fastened to their adjacent sides. -T ere are two bevel shown which 'mesh with both of the bevel gears so 'that movement of one of the totalizer-wheels will rotate the other one of the pair in the opposite direct-ion.v l

The above mentioned construction, as shownjn the Fuller patent, necessitated the spacing of the adding and subtracting lwheels pinions a suiicient distance apart to provide room for the bevel gears and lpinions which co-i operate with both wheels. spacing had to great that it was possible to put only one adding and subtracting totalizer onto a totalizer lii1e,'such` as is well known in thesemachines. In the present "invention,

however, a constructioh is provided. which which accompanies and forms part of this 25 spectieationY.V i

' tractin permits the adding and subtracting totaliier wheels to'be placedclose together, therebyallowing a plurality of adding and subtract'- in totalizers te be mounted on the same tota `'zer line. In Figf 11 it will be noted that there are three adding and subtracting totalizers andone adding totalizer 'all mounted on thesame line; Such an; arrangement is.' n

extremely useful, ,as it triples thenumber of adding and subtracting totalizers that can besuc'cessfully actor. y

'onstmcton of 4 talzef units' consists Yof anad wheel 30 andasub'- wheel 31. ese. wheels are-loose on a tu 32,-suppo'rted at its right hand end (Fil) by a bracket 33, and at its-left. hand end a bracket 34' both slidablymounted used in machines of thisgcharadding and wea-wieg 'ta' y .v0v oftheadding and subtracting units i on a' shaft 35 slidab y mounted in the usual plates '33v (one only shown) to thev machine side frames 37. Securedftothe Een, Nq; 17,242,170, grama oct. 9,2191?, @eimer sides ofthe so encarar@ gears 38 and 39 (Fig. 3). Between the gears 38 and 39 is a rmg 40 which carries an interiorly projecting lug 41 cooperating with a spline 42 in the tube 32. This construction 5 permits the endwise movement of the ring 40 on the tube to assemble the ring on the tube, but prevents any rotating movement about said tube during operation of the machine. The ring 40 has an extension 43 (Fig. 5) which carries a pin 44, on which is loosely mounted a pinion 45. The extension 43 also carries a pin 46 on which is loosely mounted a pinion 47. The extension 43 is wider than the ring 4,0 and is counterbored on opposite sides at 48 and 49 to receive the pinions 45 and 47 respectively, The pinion 45 is located to meshwith the gear 38, andis held from lateral movement by the adding wheel 30. y.The pinion 47 il located to mesh with the gear 39, and is feld from lateral movement A by the subtracting wheel 31. These pinions 45 and 47 areof suilicient width to mesh with each other at the place where the counterbored holes overlap or communicate with each other. It can be seen from Fig. 3 that if the adding wheel is rotated clockwise, the pinion 45, which meshes'with the gear 38, will be rotated counter-clockwise, the pinion 47 which meshes with the pinion 45 will be rotated clockwise, and the gear 39 and subtracting wheel 31 will be rotated counter-clockwise, that is, in the opposite direction from that of the adding Wheel 30. Thus any movement given to one of the two wheels 30 or 31 will rotate the other' wheel of the pairinl the opposite direction to the .same extent. Y

Shifting. mechanism As above mentioned, all of the adding and subtracting totalizer' wheels l are loosely mounted on the tube 32, andthe means .for

shifting this tube and the totalizer wheels laterally to position any desired set of totalizer ralit of actuating segments (Fig: -1) Awill f now e described. The bracket 34, w ich supports the left hand end of the tube 32,`carries' a boss 51 in which is mounteda rod 52 carryingrflangedrollers 53. The Vlower roller 53 l operates in a cam slot 54 formed in' a segmental cam 55, fast on asleeve, 56 supported by a stud 57 carried by the side frame. Upon the operation of the machine, the cam 'is ed tofand fro laterally of the machine, de

-lar bracket 58 projecting laterally from the wheels ina position to cooperate with a plu' pending upon Which'totalizer is to be operated and whether it is to be an adding or a subtracting operation'.l The parts are guided in their lateral movements by a slotted anguside frame of the machine and harving a slot- 59 formed therein in which the upper roller 53 operates".

When an adding key is depressed, the cam 55 will cause the adding totalizer wheels of the corresponding totalizer to be positioned in alinement with the actuating segments 50, and if a subtracting key is depressed the cam will cause the subtracting wheels 31 of the corresponding totalizer to be moved into alinement with the actuating-segments 50. It can be seen from Fig. 1 that the single adding totalizer is in alinement with the actuating segments. This totalizer is mounted on this. totalizer line, in addition to the adding and sub-. Ctrac'ting totalizers.

After the totalizer wheels have been positioned, in accordance with the control key depressed, they 'are moved into engagement with the actuators.J The means for eiiecting this engagement is very well known and is described in the above mentioned Fuller patent, and therefore no showing or description thereof is included herein. A stationary aliner 60 is provided for each totalizer line. These are identically the same as the aliners shown in the Fuller patent with the exception that a plurality of notches 61 are formed inl said aliners to permit either the adding or subtracting wheel to rotate when the other 10u- -fulfill the objectsprimarily stated, it is to be understood that it is not intended lto confine y the invention to the one form or embodiment Y herein disclosed, for it is susceptible of emu bodiment in various forms, all coming within the scope of the claims which follow.

What is claimed is 1. An adding and subtracting totalizer in.. cluding adding and subtracting elements, means operatively connecting said elements and means including the adding and subtracting elements to hold the -cpnnecting means in functioning position.

2. .An adding and subtracting totalizer including adding and subtracting wheels, al member for sup orting the same, pinions connecting said W eels, a plate non-rotatably 120 mounted on said member-for supporting said pinions,v means for holding said wheels against longitudinal movement on said memp ber, the parts being arranged so thatl each adding andsubtracting wheel retains its reppective pmion on said` plate.

3.- In an adding and subtracting totalizer;

the combination of a 4single non-rotatable shaft; 4totalizer elements rotatably mounted on the shaft; a non-rotatable support between 13 0 the totalizer elements in position to contact the adjacent sides of both totalizer elements; and intermeshing inions rotatably mounted on the sup ort aus held against axial movement by t e support and the totalizer elements, said pinions also meshing with the totalizer elements tov rotate the totalizer elements in opposite directions when either ele-4 ment is rotated in either direction.

In testimony whereof I aix my signature.

CHARLESVH. ARNOLD.
